With its bi-directional and flexible power characteristics, energy storage can effectively solve the security and stability issues brought by the integration of distributed power generation into the distribution network, many researches have been conducted on the urban distribution networks.
1) Economic performance improvement: After energy storage planning, the total operation cost of the rural distribution network decreased from 5.9665 million CNY to 5.2851 million CNY, representing an 11.4% reduction.
The purpose of energy storage system planning is to store the surplus electricity generated during the process of new energy generation, thereby reducing the costs associated with curtailed wind and solar power, enhancing the economic efficiency of power system operation, and ultimately lowering the overall cost of distribution networks.
The results demonstrate that the optimized energy storage planning significantly reduces the operational costs of the rural distribution network, decreases electricity purchasing expenses and curtailment losses of wind and solar energy, and optimizes power flow distribution while enhancing nodal voltage stability.
